When the E1/T1B bit of the Global Configuration register is a logic 1, this register is held reset.
This 8-bit register selects the Activate code sequence that is to be detected. If the code sequence
length is less than 8 bits, the first 8 bits of several repetitions of the code sequence must be used
to fill the 8-bit register. For example, if code sequence is a repeating 00001, the first 8 bits of two
repetitions (0000100001) is programmed into the register, i.e.00001000. Note that bit ACT7
corresponds to the first code bit received.
